I tried a couple of different options, after I had my last baby, and ended up with an IUD. I don't have to remember to take anything. It doesn't mess with your hormones, and my insurance covered most of the cost. It's long term though, (lasts about 10 years), so it's something you want to do if you don't plan on having any more kids for a while.
There are two different types of IUDs, one with hormones, and one without. I opted for the one without, because the hormones in the Pill really messed with me. It's been working great for two years now, and I don't even realize it's there.
Good luck!
